Waterfront due diligence, in the order it has to happen.
A waterfront home either fits your boat or it does not, and no negotiation changes a fixed bridge. These are the six checks we run on every Fort Lauderdale and Broward waterfront purchase, the question to ask on each one, and the sequence that keeps you inside your inspection period.
Published · Updated · Data cutoff
Bridge clearance and fixed bridges
Measure the boat's air draft against every bridge between the dock and the inlet. A fixed bridge sets a hard ceiling that no scheduling can solve; a bascule bridge sets an opening schedule you will live with daily. Confirm clearance at mean high water, not at the number a listing repeats.
Ask
Which bridges sit between this dock and the ocean, and what is the lowest clearance at high tide?
Ocean access and inlet route
"Ocean access" is a marketing phrase until the route is drawn. Confirm the actual path, the inlet used, the run time, and whether the route is affected by no-wake zones or seasonal manatee restrictions.
Ask
Draw the route to the inlet and time it. Is it ocean access, or ocean access with a bridge?
Seawall condition and ownership
Seawall replacement is one of the largest unbudgeted costs on a waterfront home. Look for cap cracking, tie-back failure, voids behind the wall, and settled patio slabs. Confirm who owns and maintains the wall and whether a municipal elevation standard now applies.
Ask
How old is the wall, when was it last inspected, and does it meet the current elevation requirement?
Dockage rights and dimensions
Usable dock length, water depth at low tide, pilings, power and water service, and whether a lift is permitted. Check that the dock as built matches what was permitted — unpermitted dock work transfers to you as an open problem.
Ask
What is the depth at mean low water, and is the dock and lift permitted as built?
Flood zone, elevation and insurance
Pull the FEMA flood zone and the elevation certificate before you price insurance. Zone, first-floor elevation and construction type drive the premium more than the purchase price does. Get a real quote in writing during the inspection period.
Ask
What is the flood zone and base flood elevation, and what does the actual bound premium look like?
Permits, encroachments and survey
Order a current survey with the waterway boundary shown. Check open or expired permits, davit and boat-lift approvals, and any encroachment over the property line or the submerged-land boundary.
Ask
Is there an open permit, and does the survey show anything crossing the waterway boundary?
The sequence
- 01Before the offer: confirm bridges, air draft and the inlet route. This is the only check that can make a home unusable regardless of price.
- 02Days 1–3 of inspection: order the survey, request the elevation certificate, pull permit history.
- 03Days 3–7: seawall and dock inspection by a marine contractor, not a general home inspector.
- 04Days 5–10: bind an insurance quote in writing using the elevation certificate.
- 05Before the deadline: price every open item and either negotiate it or withdraw. Waterfront items do not get cheaper after closing.
How this was built
Data cutoff:
- The checklist is drawn from waterfront transactions we have handled in Broward and Miami-Dade, and from the items that actually caused a renegotiation or a withdrawal.
- We do not publish per-property clearance, depth or seawall figures on this page. Those come from a current survey, the permit file and a marine inspection for the specific address.
- Flood zone and base flood elevation are read from the FEMA flood map service and the property's elevation certificate — never from a listing remark.
- Bridge clearance is verified against NOAA charts and the operating authority's published clearance, at mean high water.
- Insurance figures are only used once a carrier has quoted the specific property in writing.
This is a diligence checklist, not marine-engineering, insurance or legal advice. Seawall and dock condition must be assessed by a licensed marine contractor.
